Question
Power = 3 kWWork done = 825 kJCalculate the time.Time = _____ s
Solution 1
To calculate the time, we need to use the formula for power, which is:
Power = Work done / Time
We can rearrange this formula to solve for time:
Time = Work done / Power
Given that Power = 3 kW = 3000 W and Work done = 825 kJ = 825000 J, we can substitute these values into the formula:
Time = 825000 J / 3000 W = 275 seconds.
Solution 2
To calculate the time, we need to use the formula for power, which is:
Power = Work done / Time
We can rearrange this formula to solve for time:
Time = Work done / Power
Given that Power = 3 kW = 3000 W and Work done = 825 kJ = 825000 J, we can substitute these values into the formula:
Time = 825000 J / 3000 W = 275 seconds.
